1. The Periodic Table

2. Quiz Write the symbol of the following elements 1. Lithium 2. carbon
3. oxygen
4. Sodium
5. Aluminum

3. Quiz- identify the colored areas of the periodic table on the next slide

4. What are the different areas of the table?
What are each of the groups.

5. What are groups and periods

6. Why do elements in the same group have similar properties
Why do elements in the same group have similar properties? Like why do all alkali metals blow up in water?

7. You see trends on the periodic table

8. Increasing atomic radius vs. large # of protons

9. Increasing atomic radius

10. Before we can learn about any more trends we gotta learn a new word
Maybe two?

11. What is an ion? How do we write an ion?

12. Nova about ions here

13. Electron affinity vs. ionization energy
Where on the table do elements want electrons really bad and are willing to steal them from anybody?

14. Exact Definitions
Electron Affinity- theamount of energy released when an electron is added to a nuetral atom (how much do I want one)
Electronegativity- a measurement of the attraction of an element for electrons (how good am I at attracting electrons)
Ionization energy- the energy needed to remove an electron from an element (can I pull off an electron easily)

15. What is an isotope It has a different number of ___________?
Why?______________
What difference does it make?__________
What sentence do we use to memorize this?

16. Nova isotopes

17. Ipads and worksheets?

18. What in the world is average atomic mass?
Look at the weight on the period table for magnesium
How many nuetrons does it have?
Why are we rounding?

19. How do I find the average?
Carbon has two stable isotopes
Carbon 12 is 98.89% of the total
Carbon 13 is 1.11% of the total
To find the average change the % to a decimal
Multiply the decimal by the weight
Add the two numbers together.

20. Worksheet Time- ave atomic mass

21. Day 2 Quiz
1. What is different between an ion of lithium and an atom of lithium?
2. How do you write the symbol for an atom of calcium?
3. How do you write the symbol for an ion of calcium?
4. Write the atomic symbol for Carbon showing both the atomic number and mass
5. Write the atomic symbol for an isotope of carbon which contains 2 extra neutrons

22. Nova on the bottom elements
